Stereo Mini (male)• Typical connection for microphones, headsets, and computer speakers.• Two bands = stereo One-bans = mono
RCA (male)• Typical connector for audio and video in non-computer systems. (i.e. stereos & TVs)• In the PC world, typically used to connect the second speaker (and sub-woofers) to the first one.
USB Type A Outlets• Universal Serial Bus• Most common peripheral connector today.• Allows up to 127 devices.• Hot swapping• Current version 2.0: 480Mbits/second• 4.375V to 5.25V powered from the computer.
USB Type A• The end of the cable that will plug into the computer.• Sometimes devices will also use this type of outlet.• Rectangular
USB Type B Full-Size Outlet• Typical connector for the device being used.
USB Type B Full-Size• Plugged into the device.• Square-ish
USB Type B Mini Outlet• Smaller devices will have this type of outlet.
USB Type B Mini• Typically used to connect to smaller USB devices such as card readers and digital cameras.
PCMCIA Slot• Personal Computer Memory Card International Association• People Can’t Memorize Computer Industry Acronyms• Used in laptops• Card inserted into slot
PCMCIA Card• Expansion cards for laptops• Modems, WiFi, wired networking, biometric security.• Mostly replaced by USB.
Parallel (male)• Older printers• This end connects to the computer.• Mostly replaced by USB.
Parallel (female)• Older printers• This end connects to the printer.• Mostly replaced by USB.
SCSI Port (female)• Small Computer System Interface• External hard disks, tape drives, scanners, printers.• Popular with Apple & Sun systems.• Never really caught on in the PC world but did get used in some systems.• Mostly replaced by USB.
SCSI (male)• End that connected to the computer.
SCSI (device end)• End that connected to the device.• Devices connected in a “chain”.• Device #2 would be connected to device #1 with a cable having this type of connector at both ends.
IDE Outlet on Motherboard (male)• Motherboard will typically have several of these.• Use to connect storage devices such as hard-, CD/DVD- and floppy-drives.
IDE Ribbon Cable• Connects storage devices to the motherboard.• Solo end connects to motherboard, dual end connects to device(s).• End connector must be used before a middle connector.• Not all cables have middle connectors.
IDE (female end)• The plug at the far end connects to the motherboard.
IDE (female middle)• Many IDE cables have a connector in the middle, but closer to one end than the other.• This connector must be used last.
Hard Drive• IDE outlet (male)• Power outlet (male)• Jumpers – Master – Slave – Cable Select
CD-ROM/DVD Drive• IDE outlet (male)• Power outlet (male)• Jumpers – Master – Slave – Cable Select• Digital and/or Analog audio outlets (male)
P5 Power Plug (female)• Larger of the two types of power plugs.• Connects to devices that need more power such as hard drives and CD/DVD drives.
P7 Power Plug• Smaller of the two types of power plugs.• Connects to devices that need less power such as floppy drives and Centurion Guard.
PCI Slots• Peripheral Component Interconnect• Slots for connecting cards to the motherboard.• Mostly replaced by USB.
PCI Connectors• “Break” in the board allow the card to only be plugged in in one direction.
PCI Networking Card• Example of one of the few remaining cards that a PC will have.
Memory Slots• If you have four slots memory must be inserted in matched pairs.• If you have two slots you can fill them any way you wish.
RAM• Break in card prevents it from being plugged in backwards.• Make sure you get the right type for your computer. – SIMM vs. DIMM (single vs. dual) – DRAM vs. SRAM (dynamic vs. static) – Parity vs. Non-Parity Modules
Internal Battery• Keeps the computer’s clock running when the computer is off.
